The casing 11 is provided with a plurality of through holes 12 penetrating in the plate thickness direction. The through holes 12 have a size and a number necessary to reduce a differential pressure generated before and after the driven plate 8 when the wet multi-plate lock-up device is not operated. For example, about 16 through holes having a diameter of about 2φ are provided. . In addition, 13 is a core plate spline part.

When the pressure difference due to the flow inside the torque converter occurs before and after the driven plate 8 approaches the driven plate 8 to one side, the pressure difference between the front and rear is reduced by the through hole 12, and the driven plate 8 is moved to one side. It will not be sent.
【００１４】従って、非締結状態でも、ドライブプレー
